High frequency switching and ultra low voltage drops provide very high efficiency and silent operation. Costs, heatsinking requirements and motor and battery losses are reduced. Low end torque, range and battery life are increased.

Environmental protection provided by a rugged, sealed (factory serviceable) anodized aluminum extrusion housing. Simple mounting and wiring with push-on type connectors for control signals. Plated solid copper busses used for all power connections.

Thermal protection and compensation circuit provides undertemperature cutback, constant current limit over operating range, and linear rollback in over-temperature. No sudden loss of power under any thermal conditions.

High pedal disable option prevents controller operation if the key switch is turned on while throttle is applied.

Static return to off option prevents controller operation if the keyswitch is turned on while a forward or reverse direction is selected.
